ZQ500 Series User Guide
A Non-Acknowledged Alert also displays over the printer status
icons, but in this case it does not require user input to be cleared.
The alert will automatically be cleared after being displayed for
five (5) seconds.
Error Alerts also appear over the printer status icons and require
no user input via the front panel to be cleared, but they do require
the user clearing the error condition by other means. The Error
Alert will remain on the display until the error condition is cleared.
Power Saving Features
The ZQ500 Series printers have a few key features designed to
extend the life of the battery. These features are described below.
Sleep Mode
The Sleep Mode feature is a way the printer conserves battery
life whereby the printer will automatically go into a “sleep” state
after two (2) minutes of inactivity. When the printer is in this state
there will be no content displayed on the LCD in addition to no
backlight. The printer will indicate Sleep Mode by a slow blinking
green LED ring around the Power Button (See Page 26).
If the Power Button is pressed for less than three (3) sec-
onds (<3), then the printer will enter Sleep Mode.
If the Power Button is pressed for more than three (3) seconds
(>3), then the printer will execute a soft power down.
In order to “wake up” the printer, the user must press the Power
or Select buttons for less than three (3) seconds, or the print-
er will wake up on its own when communication is initiated via
Bluetooth. If the Power Button is pressed for more than three (3)
seconds, the printer will wake up and shut down completely.
